KSZ8852HLE
Two-Port 10/100 Mb/s Ethernet Switch with
8 or 16-Bit Host Interface
Revision 1.1
General Description
The KSZ8852 product line consists of industrial capable
Ethernet switches, providing integrated communication for
a range of Industrial Ethernet and general Ethernet
applications.
The KSZ8852 product enables distributed, daisy-chained
topologies preferred for industrial Ethernet networks.
Conventional centralized (i.e., star-wired) topologies are
also supported for fault tolerant arrangements.
A flexible 8 or 16-bit general bus interface is provided for
interfacing to an external host processor.
The wire-speed, store-and-forward switching fabric
provides a full complement of QoS and congestion control
features optimized for real-time Ethernet.
The KSZ8852 product is built upon Micrel’s industry-
leading Ethernet technology, with features designed to
offload host processing and streamline your overall design:
• Wire-speed Ethernet switching fabric with extensive
filtering
• Two integrated 10/100BASE-TX PHY transceivers,
featuring the industry’s lowest power consumption
• Full-featured QoS support
• Flexible management options that support common
standard interfaces
A robust assortment of power management features
including energy-efficient Ethernet (EEE) have been
designed in to satisfy energy-efficient environments.
